Comparing: Pz.Kpfw. V/IV Alpha vs. VK 30.01 (D) vs. Type 4 Chi-To

Only one prototype was built. The Pz.Kpfw. IV turret was mounted as a stationary module on the Panther hull for testing.

In the winter of 1941–1942 the WaPrüf 6 issued technical requirements for a new 30-ton tank. The orders for development were placed with MAN and Daimler-Benz. The prototypes were to be ready by May 1942. However, on May 13th, 1942 only comparative characteristics of the projects were submitted. The MAN's project was preferred, and the Daimler-Benz's project was canceled.

The Type 4 Chi-To medium tank was developed in 1943 on the basis of the Chi-Nu. The tank was conceived to replace the Chi-Ha. However, mass production was not launched due to shortages of materials and components. A total of six chassis were produced, and only two tanks were built on their basis.
